That depends on how the multiple paths are used by your routers' forwarding mechanisms. CEF multipath usually hashes over source+destination IP address, so all traffic between a pair of hosts should use the same path. The Cat6500/7600 has an option where (TCP/UDP) port numbers are also included in the hash, so traffic between a single pair of hosts could use multiple paths, but all packets of a single transport connection (TCP or UDP) would stay on the same path. I.e. if you have a fancy stereophonic VoIP implementation that uses one RTP flow for each channel, then that application should have extra-good jitter buffering in case the left-ear samples use a different path from the right-ear samples. But all real-time applications should have (adaptive) jitter buffers in this day and age, right? -- Simon. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
